The interest in buccal drug delivery is under consideration due to some distinct properties compared to the traditional pharmaceutical formulations for oral administration: significantly higher bioavailability, a faster absorption rate of the drug, and substantial compliance for special needs patients. Oral films are obtained through various technologies, from conventional tools to 3D and 4D printing approaches. This minireview aims to describe the current additive manufacturing technologies in oral film fabrication, display their advantages and limitations, and discuss various formulation strategies. It also provides advanced data regarding synthetic and natural polymers used in 3D printing technologies for oral films. Moreover, it shows the most recent studies with 3D-printed orodispersible films and mucoadhesive buccal films manufactured through previously analyzed methods. Finally, conclusions and future perspectives are also briefly summarized.

En este trabajo se presenta el desarrollo de la metodología del diseño mecánico para el diseño conceptual de una máquina de pruebas de tensión en elastómeros. Mediante el método del QFD, se identifican los requerimientos del cliente, las especificaciones de ingeniería, así como los objetivos y umbrales de diseño a lograr. Posteriormente, se aplica el método de diseño por funciones para generar una tabla de subfunciones y una tabla morfológica de conceptos que podrían satisfacer cada subfunción. La evaluación de conceptos se realzó mediante las matrices de Pugh. Después, se generaron conceptos de diseño en CAD, donde se integran los diferentes elementos seleccionados previamente. Nuevamente se ocupan las tablas de Pugh para seleccionar el concepto integrado ganador. Se realizó el cálculo analítico del torque requerido en el motor para llevar a cabo la prueba de tensión en elastómeros. Asimismo, se realizó una simulación de esfuerzos, desplazamientos y factor de seguridad, para evaluar la resistencia de los elementos críticos.

“…Widely employed thermoplastic matrix materials include polyphenylsulfone (PPSU), polyether ether ketone (PEEK), and polyaryletherketone (PAEK), while polyethylene terephthalate glycol (PETG) and polylactic acid (PLA) emerge as common choices [15]. Characterized by thermal resilience and flexibility, PETG finds application, whereas PLA, esteemed for its biodegradability, cost-effectiveness, and high stiffness, boasts a green footprint [16,17].…”

Fused deposition modeling (FDM) 3D printing is widely utilized for producing thermoplastic components with functional purposes. However, the inherent mechanical limitations of pure thermoplastic materials necessitate enhancements in their mechanical characteristics when employed in certain applications. One strategy for addressing this challenge involves the incorporation of reinforcement materials, such as carbon fiber (CF), within the thermoplastic matrix. This approach leads to the creation of carbon fiber-reinforced polymer composites (CFRPs) suitable for engineering applications. The utilization of CFRPs in 3D printing amalgamates the benefits of additive manufacturing, including customization, cost-effectiveness, reduced waste, swift prototyping, and accelerated production, with the remarkable specific strength of carbon fiber. This study encompasses tensile and compressive testing of distinct material compositions: recycled polylactic acid (rPLA), PLA enriched with 10 wt.% carbon fiber, pristine polyethylene terephthalate glycol (PETG), and PETG bolstered with 10 wt.% carbon fiber. Tensile tests adhere to the ASTM D3039 standard for specimens of rectangular shape, while the ASTM D695 standard governs the compressive testing procedures. Additionally, an inquiry into the influence of the primary 3D printing build orientation parameter on the tensile and compressive strengths of diverse materials was conducted. The outcomes reveal that rPLA exhibits superior mechanical properties in both tensile and compressive tests, irrespective of flat or on-edge build orientations. In the context of tensile strength analysis, it is noteworthy that rPLA demonstrated a superior performance, surpassing CFPLA by 30% in flat orientation and exhibiting a remarkable 39.2% advantage in on-edge orientation. Moreover, PLA reinforced with carbon fiber exhibits superior tensile and compressive properties compared to its PETG counterpart. A comparative analysis between CFPLA and CF-PETG indicates that CF-PLA demonstrates higher tensile strengths, with increases of 26.6 and 27.6% for flat and on-edge orientations, respectively. In the context of compressive strength analysis, rPLA surpassed CFPLA, PETG, and CF-PETG by 23.7, 53, and 67%, respectively. Intriguingly, the findings indicate that the incorporation of 10 wt.% carbon fiber diminishes the tensile and compressive properties in comparison to pure PETG.
